' vention is to provide an air cleaner which will be of simple construction and capable of being'man ufacturedand retailed at a low price. v 15 These and various other important objects and advantages of theinvention will become appareat to the reader of the following specification.

' In the drawings:

Referring to the drawings wherin like nil-- merals designate like parts, it can be seen that numeral represents the shellwhich contains a,

body of filtering material 6. The bottom of this 35 shell 5 is inclined, as at 1, and is provided with a drain plug 8. One end of the shell 5 is provided with an extending tube 9 to which the carburetor can be connected (not shown).

4 The other end of the shell 5 is providedwith a ings ll therein. At the central portionof this closure I0 is a bearing l2 through which the pin l3 extends, this pin extending through the closure I! so as to support the annulus M from which extend the fan blades i5 and also the arms I which carry the spoons l'|.' The end of the shell 5, adjacent the end wall i 0, is provided with a basin it which communicates with the deep portion 1a 'of the bottom 1 by means of the conduit i9. This basin I8 is located so that the spoons II will dip into the liquid content thereof, as the rotor assembly, generally referred to by numeral 20 and including th ll blades II and spoons l1, rotates. I v

Figure l is an end elevational view of the deremovable end wall ill having screen-filled open-' .the spirit and scope of the invention as claimed The purpose ofthese spoons I1 is 'to lift the filter fluid from the fluid basin ll, moving the same upwardly and throwing it toward the cup 24, which cup is open at its top. This cup 24 has an opening in the bottom thereof to loosely re- 6 ceive the guide pin 25 which extends through the opening and is provided at its upper end, within thecup, with a stop 24' against which the cup can abut when in a raised position. The guide pin 23 extends from the free end of the conduit 22, which conduit has its opposite end embedded in the mass of filtering material 6. The embedded end of the conduit 22 is provided with perforations 22"through which the fluid can reach the filtering element 6. I ll Referring to Figure 5 it can be seen that reference character 24c denotes the bracket supported by the inside of the shell 5. An upstanding member is provided on the bracket and on this is rockably mounted the arm 24d, this arm having a weight eat one end and being attached at its opposite end to the cup 24. The weight 24c is suflicient to lift the cup 24 when the latter is empty and no fluid is being supplied by the spoons [1. -When the cup is empty it rises 25 until it is stopped by the pin head 24'.

In this empty condition operation of the cup 24,' the arm 24d pushes the pin 25 upwardly, which in turn" drives the contact 26 against the contact 21,-thus closing an electrical alarm cir-- cult including an indicating lamp 28 or some other form of signal. The pan 2i supported by the outer end of the conduit 22, simply serves as av rest, for the cup 24 when the latter is in depressed position due to a volume of fluid therein.

' Obviously when the engine is running, air will be sucked through the mesh-filled windows II and through the filtering material 6 to pass out through the tubular connection 9 to the carbureter. In,v this travel of the air, the air will 40 pass through the rotor 20 and cause rotation thereof and this rotation of the rotor will cause a supply of liquid to be passed to the filtering body 6. Thus the filtering body 6 will be impregnated with liquid and this will materially assist inthe collection of dust and the elimination of dust from the air before it passes into the carbureter.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from hereinafter. 66
